LangGraph - Pros & Cons
Pros
- ✓Open-source library is MIT-licensed and runs anywhere without platform lock-in

- ✓First-class multi-agent patterns: supervisor, hierarchical, sequential, parallel branches
- ✓Tight integration with LangSmith for production observability, evaluations, and replays
- ✓Active maintenance from the LangChain team with frequent releases and strong community
Cons
- ✗More verbose than LangChain for simple agents — explicit state schemas and edge functions add overhead
- ✗LangSmith trace pricing ($2.50/1k base traces) is a real cost at production scale
- ✗LCU + deployment-minute billing makes pricing harder to predict than seat-only competitors
- ✗Steeper learning curve than role-based frameworks like CrewAI for newcomers
- ✗Best documented in Python; JavaScript SDK exists but lags in features
